To find the ratio of the number of students who want iced tea to the number of students who want lemonade, we can follow these steps:
-
Determine the number of students who want iced tea.
- There are a total of 30 students.
- 13 students want lemonade.
- Thus, the number of students who want iced tea is: \[ 30 - 13 = 17 \]
-
Write the ratio.
- The ratio of the number of students who want iced tea to the number of students who want lemonade can be expressed as: \[ \text{Ratio} = \frac{\text{Number of iced tea lovers}}{\text{Number of lemonade lovers}} = \frac{17}{13} \]
So, the ratio of the number of students who want iced tea to the number of students who want lemonade is 17:13.
